A car of mass 860.0 kg accelerates away from an intersection on a horizontal road. When the car speed is 39.6 km/hr (11.0 m/s), the net power which the engine supplies is 5700.0 W (in addition to the extra power required to make up for air resistance and friction). Calculate the acceleration of the car at that time.

Answer 1

power=work/time=force*velocity
solve for force.

then acceleration=force/mass
